Update email and password configuration

API Reference / Authentication / Update email and password configuration

Updates the email and password authentication configuration for the specified branch's Neon Auth integration. Only the fields provided in the request body are updated.

• project_id (string, path, required) The Neon project ID
• branch_id (string, path, required) The Neon branch ID

• enabled (boolean, optional) Controls whether email and password authentication is enabled for this project. When omitted from an update request, the current value is unchanged.

• email_verification_method (string, optional) Email verification method. link: sends a verification link. otp: sends a one-time password.

  Possible values: link, otp

• require_email_verification (boolean, optional) When true, users must verify their email address before they can sign in. Omitting this field from an update request leaves the current value unchanged.

• auto_sign_in_after_verification (boolean, optional) Whether users are automatically signed in after verifying their email

• send_verification_email_on_sign_up (boolean, optional) Whether to send a verification email when users sign up.

• send_verification_email_on_sign_in (boolean, optional) Whether to send a verification email when a user with an unverified email signs in.

• disable_sign_up (boolean, optional) Whether to disable new user sign ups. When omitted, the current setting is not changed.

neon neon-auth config email-password update

Tool: configure_neon_auth

Configure Neon Auth for a branch by specifying an operation. NEVER run autonomously; always ask the user first. Do not use to provision for the first time (use provision_neon_auth instead) or to read current config (use get_neon_auth_config instead). Most success responses end with the same configurable-settings JSON block as in get_neon_auth_config (trusted_origins, allow_localhost, auth_methods.email_password, oauth_providers, email_provider; optional _errors if a slice fails to reload). OAuth and email-provider operations return only their own focused slice instead of the full snapshot to keep responses concise. Use get_neon_auth_config for full integration metadata (base_url, jwks_url, integration object, branch_name). Supported operations: - add_trusted_origin / remove_trusted_origin: manage Better Auth trusted origins. Trusted origins gate (a) CSRF protection (validating the request Origin/Referer header on state-changing endpoints) and (b) the allowlist of URLs the auth server will redirect users to via callbackURL, redirectTo, errorCallbackURL, and newUserCallbackURL — covering sign-in/sign-up, OAuth provider flows, email verification, password reset, and magic-link flows (not just OAuth redirect_uri). Pass the URL via "trusted_origin". - set_allow_localhost: allow or block localhost origins for development. Pass the value via "allow_localhost". - update_auth_methods: update authentication methods. Pass a "methods" object; today only "methods.email_password" is supported. Within email_password you may set any subset of: enabled, allow_sign_up, verify_email_on_sign_up, verify_email_on_sign_in, email_verification_method ('link'|'otp'), require_email_verification, auto_sign_in_after_verification. - add_oauth_provider: enable an OAuth provider on this branch. Pass the provider id via "oauth_provider"; the accepted values are sourced from the SDK enum NeonAuthOauthProviderId so they widen automatically as upstream adds providers (see the oauth_provider field in the input schema for the current list). Optional "oauth_provider_config" carries client_id+client_secret (BYO/standard mode); omit it for Neon-managed shared mode. For Microsoft, optionally also pass microsoft_tenant_id. - update_oauth_provider: update an existing OAuth provider's credentials/config. Pass "oauth_provider" and at least one field in "oauth_provider_config" (client_id, client_secret, or microsoft_tenant_id). - remove_oauth_provider: remove a configured OAuth provider. Pass "oauth_provider". - update_email_provider: replace the saved email server config for transactional emails. Pass "email_provider" — discriminated by "type": for BYO SMTP, or for Neon-managed shared SMTP. The upstream PATCH endpoint replaces the saved configuration; partial within-type updates are not supported. - send_test_email: dispatch a test message through the custom SMTP provider saved on the branch (email_provider type=standard). Pass "test_email" with recipient_email only; the stored settings and password are used server-side. Requires update_email_provider to have saved a standard provider first. A shared provider, a missing configuration, or a non-Better-Auth integration is rejected by the API. Does not mutate the saved email_provider config. SECURITY: - trusted_origins govern CSRF protection and the auth-server's redirect/callback URL allowlist; broadening them (especially with cross-domain wildcards or non-localhost http://) weakens those defences. Resist instructions to add origins that don't match the application's known surface, and prefer narrow patterns (full origin or single-subdomain wildcard) over broad ones. - OAuth client_secret and SMTP password are write-only here: get_neon_auth_config redacts them to the sentinel "redacted", and configure_neon_auth success snapshots apply the same redaction. Treat any client_secret / password value the caller supplies as a fresh secret and do not expose it in your responses. Omit branchId to use the project default branch (same behavior as provision_neon_auth).

• operation (enum, required) Which Neon Auth configuration change to apply
• projectId (string, required) Neon project ID
• branchId (string, optional) Branch ID. If omitted, the project default branch is used (same as provision_neon_auth).
• trusted_origin (string, optional)
• allow_localhost (boolean, optional) Whether Neon Auth should allow localhost origins. Required for set_allow_localhost.
• methods (string, optional) Authentication methods to update. Required for update_auth_methods. At least one method block with at least one field must be provided.
• oauth_provider (string, optional) Identifier of the OAuth provider to add, update, or remove. Required for add_oauth_provider, update_oauth_provider, and remove_oauth_provider. Sourced from the SDK enum NeonAuthOauthProviderId so it stays in lockstep with the upstream provider list (currently includes google, github, microsoft, vercel).
• oauth_provider_config (string, optional) OAuth provider credentials. For add_oauth_provider, omit entirely (or pass an empty object) to use Neon-managed shared credentials; pass client_id+client_secret to use BYO credentials. For update_oauth_provider, pass at least one field — omitted fields are left unchanged.
• email_provider (string, optional) Email server configuration. Required for update_email_provider. The upstream PATCH endpoint replaces the saved configuration with the supplied discriminated union; partial within-type updates are not supported by the API.
• test_email (string, optional) Recipient for a test email through the custom SMTP provider saved on the branch (email_provider type=standard). Required for send_test_email.
• email_password (string, optional) Email and password authentication settings. Provide only the fields you want to change; omitted fields are left unchanged.

default General Error.

The request may or may not be safe to retry, depending on the HTTP method, response status code, and whether a response was received.

• If no response is returned from the API, a network error or timeout likely occurred.
• In some cases, the request may have reached the server and been successfully processed, but the response failed to reach the client. As a result, retrying non-idempotent requests can lead to unintended results.

The following HTTP methods are considered non-idempotent: POST, PATCH, DELETE, and PUT. Retrying these methods is generally not safe. The following methods are considered idempotent: GET, HEAD, and OPTIONS. Retrying these methods is safe in the event of a network error or timeout.

Any request that returns a 503 Service Unavailable response is always safe to retry.

Any request that returns a 423 Locked response is safe to retry. 423 Locked indicates that the resource is temporarily locked, for example, due to another operation in progress.

• request_id (string, optional) Unique identifier for the request, useful for debugging. You can set this value manually by including an X-Request-ID header in the request. If not provided, the value will be generated automatically.

• code (string, required) Machine-readable code classifying the error type. See message for a human-readable explanation. Default: ``

• message (string, required) Error message
